[Bluez-users] [Bluetooth-alsa] Bluetooth headset via SCO problem

Hi there,
I have followed the building steps that are reported in the bluetooth-alsa
website (http://bluetooth-alsa.sourceforge.net/build.html).

As I have a mono headset (phone+mic) I want to use the SCO mono protocol.
First question: I am in wrong with this decision?

When I try to play some music files with the aplay like -> "aplay -D headset
/usr/share/wengophone/sounds/ringin.wav" I receive this message -> "Unable
to set number of SCO buffers : please upgrade your Kernel !"

I can connect with the device as the system ask me for the pairing code and
I see from the headset that the connection between the devices appears to be
good, but I receive anyway that message.

Anyone has experienced something like that yet or have some advice to give
me?

Thanks all,
Best Regards,
Advhertz.
